TOY MACHINE-GUN.

adapted to detonate a series of explosive charges carried by a flexible strip or ribbon, Without, however, throwing or dis charging any sort of a projectile. It is the object of my invention to provide a toy firearm of the class indicated, imitating in appearance and action the so-called automatic or machine guns used for military purposes.

In the accompanying drawings Figure 1 is a side view of gun em yin my invention, Fig. 2 is a partial longitudmal vert 1cal section thereof, Fig. 3 is a longltudlnal vertical section lookmg oppositely from the same plane as in Fig. 2, Fig. 4 is a detail side view of the grip and breech portion of the gun, Fi 5 is a transverse vertical section on'the p ane of the line 5-5 of Fig. 4, and Fig. 6 is a detail section on the honzontal and offset line 66 of Fig. 3. In Fig. 5 the planes of section of Figs. 2 and 3 are indicated by the broken line and arrows 2-2 and 33, respectively.

As above mentloned, the toy gun provided by my invention is intended to imitate a machlne-gun, and in pursuance of this object the gun proper is preferably mounted, as shown in Fig. 1, u on a foldable trlpod B of which the hea has a stem fittlng revolubly in a recess 7 in the gun-stock 8 at a point near the center of gravlty of the gun, -so'- that the latter will balance upon, nd may be. traversed about, the pivotal support thus formed. The stock 8 may be of wood, and a metal barrel 9 is secured theretoby suitable means such as the screws 7 10. The principal operating mechanism of the gun is inclosed 1n a cast metal breech casing formed by similarly shaped right and left side-pieces 11 and 12, of which the front portions fit upon the sides of the stock 8, while the lower and rear portions form a pistol-grip 13. The flanged edges of the two casing parts fit together at a plane intermediate t e lateral faces thereof, and the parts are separably secured together Specification of Letters Patent.

sides of the stock 8 and pivotally connected therewith by a transverse bolt 17. The cover may be swung upwardly, as indicated by the arrows a in Fig. 4, to expose the working mechanism.

A shaft 18 extends transversely throng the central portion of the casing, being j ournaled in the sides of the parts 11 and 12, and one end of the shaft projecting slightly beyond the latter side-piece. Said projecting end of the shaft is provided with a crank 19 of which the outer end is movable in the circular path indicated by the line b in Fig. 4. A latch 20 is pivoted on a screw 21 projecting from the side-piece 12, there be1n a stop-pin 22 extending through an opening in the latch to limit swinging movement thereof, and a spring 23 being arranged to normally hold the lower end of the latch in the path of the crank 19. The arrangement is such that the latch may swing forward far enough to clear the crank as the same is moved down past it.

On the intermediate portion of the shaft 18 there is revolubly mounted a spring-drum comprising a plate 24 and a gear 25 secured in spaced parallel relation to each other by a plurality of posts 26 extending between the outer portions thereof. A s iral main spring 27 is disposed between said plate and gear, the outer end of the spring being connectedto one of the posts 26, and the inner end thereof being connected with th shaft. A trigger 28 is pivoted on a stud 29 carried by the casing-part 12, said trigger extending down through an opening in t e lower flange of said casing-part. As shown in Fig. 2, the trigger is formed integrally with a searpiece 30 and is provided with a spring 31 adapted to hold the end of the searpiece in the path of the posts 26, whereby the same normally prevents rotation of the spring-drum formed bysaid posts, the plate 24 and gear 25. By turning the crank19 as indicated in Fig. 4, the main spring 27 may be wound to a suitable tension, retrograde movement of the crank being prevented by engagement thereof with the latch 20, and

rotation of the sprin -drum being prevented by the sear-piece 30. By pulling the trigger back toward the grip 13, the spring-drum is released so that the same may be driven by the spring. The gear 25 meshes-with a-pmion 32 secured on a crank-shaft 33 of which the ends are journaled in the casing sidepieces 11- and 12. The crank-portion of said shaft 33 has loosely attached thereto a short connecting-rod 34 which extends upwardly from the crank and has a forked end-portion straddling and pivotally connected W1th the hammer-bar 35. The latter is pivoted at one end on a shaft 36 extending transversely between the front portions of the side-pieces 11 and 12. 'The oppositeend of the hammer-bar has a head or hammer 37 of which one side is concaved as shown in Fig. 3. Said concaved side of the hammer is adapted for engagement with a cylindrical block 38 which is mounted revolubly on the shaft 18 and is fixedly connected with the gear 25. Adjoining the side of said gear the block is toothed to form a pinion 39 which drives the ammunition-ribbon feed-rollers .40 and 41. Said rollers 40 and 41 are revolubly mount ed, respectively, on arms 42 and 43 which are pivoted On the side-piece 11 as shown in Fig. 3. The upper roller 40 carries at one end a pinion 44 which meshes with the pinion 39, so as to be driven thereby, and both of the rollers 40 and 41 are knurled so that the lower roller 41 may be frictionally driven from the upper. A wire spring 45 has the ends thereof engaged with the arms 42 and 43, as shown, said spring serving to press the roller 41 up toward the roller 40, and to press the arm 42 toward the shaft 18, thereby keeping the pinion 44 in mesh with th pinion 39. Adjacent to the feed-rollers 40 and 41 there is an opening in the rearward side of the cover 16, the same having a tongue 46 which extends inwardly from the upper edge of the opening and terminates near the upper roller 40. A sheet-metal guide-trough 47 is secured to the casing-part 11 at the lower edge of the opening and extends into proximity to the lgver feed-roller 41, as shown in Fig. 3. I

The described mechanism is adapted to automatically feed and detonate a. series of small charges of explosive material arranged at uniform intervals along a ribbon or strip A of paper or the like. The charge-carrying ribbon is passed through the guide-v trough 47 and between the feed-rollers 40 and 41, thence extending forward over the upper side of the block 38, where the explosive charges are struckand detonated by the hammer 37. The used portion of the ribbon, or the fragments and debris therefrom, fall. out of the bottom of the casing through an openin provided by the omission of a portion 0 the casing member 11,

and a portion 48 of the lower flange of said member is extended up vertically so as to terminate near the block 38 and thereby tend to prevent fragments of the ribbon being carried around the block. ing the main sprin 27, and starting the end of a strip or roll of the charge-carrying rib- After fully wind-- bon through the feed-rollers, a large number of the. explosive charges may be detonated without interruption, by merely pulling the trigger and holding the same in position to release the drive-gear 25. The explosive charges may also be fired in burstsl;

of two or three shots each, by pulling and immediately releasing the trigger, so that;

the firing mechanism is stopped after the drive-gear has revolved through the angle between two of the posts 2.6. By turning the crank 19 to wind the main spring simultaneously with the discharging or firing operation, the latter maybe continued indefinitely, or as long as the ammunition-ribbon is supplied to the feed mechanism. For practice or drill with the gun, the mechanism maybe operated without the use of the ammunition ribbon, a partial simulation of gun-fire being obtained by the rapid striking of the hammer upon the block 38. From the foregoing it Will be seen that my invention provides, by comparatively simple means, a safe and durable toy gunwhich may be operated so as to closely imitate an actual machine-gun.

Now, having described my invention, what I tory hammer adapted to strike the block at one limit of its travel, and spring actuated means for driving said hammer and feeding delivered by the feeding means, a reciprocameans in unison, said driving means beingcontrolled by the trigger mechanism.

3. In a toy machine gun, a'breech casing, a motor spring disposed therein, manually actuated means for winding said spring, a rotary element actuated by said spring, a trig ger, means controlled thereby for normally preventing rotation of said element, a hammer driven by said rotary element, and a rotary block actuated by the motor spring andarranged to be struck by the hammer at one limit of its movement.
